Former Michigan safety Jordan Kovacs, an undrafted rookie free agent signee, knows how to make an impression. He was a walk-on at Michigan and rose to prominence and had something of a cult following in Ann Arbor. He knows the way to draw attention and that's hit. He did plenty of that, taking some liberties at times in the defensive backfield. He also had an interception. So he's got my attention, at least.

-------

Yes, running back Mike Gillislee was good in his first practice of rookie camp. He ran with authority. He hit the crease hard. No shuffling of his feet. No chopping. I like that. Will that translate to anything once hitting starts? No idea. But good start.

-------

The competition for kicker will be real. Kicker Caleb Sturgis connected on a couple of 50-yard tries. No, he's still not been in the fire of a pressure kick with his job on the line. But the kid kicked in The Swamp for the Gators. He's played in front of crowds much bigger than what the Dolphins will see in the preseason. I don't get the vibe that he'll be nervous.

-------

The Dolphins need to find good athletes and good system-fit players when searching for corners. Let's face it, Sean Smith wasn't a fit. He's better as a press corner. The Dolphins don't play press coverage. Jamar Taylor seems better suited for the off-man scheme the Dolphins use. And he said what he's seeing from coaches is similar to what he saw at Boise State.

“Most of it is similar, just different terminology you’ve got to get used to," Taylor said. "But most of the plays are kind of similar.”

-------

The Dolphins brought a couple of QBs to camp, including undrafted free agent Clay Belton of Findlay. He's has a way to go. A long way. His delivery is methodical. Takes too long. His accuracy is inconsistent. His footwork needs to be tightened up. He has a live arm, that's for sure. But I understand why he wasn't drafted.

-------

I mentioned Jamar Taylor above. Third round pick Will Davis looked every bit as natural and like he belonged. He had an interception. Good first day.

--------

Receivers Jeff Fuller and Brian Tyms -- both with the Dolphins last year -- were at the first day of rookie camp. Inconsistent. All I'm saying on that.
